Often regarded as forming a species-group with C. caudatus and C. garrulus, though probably more closely allied to former. May be closely related to C. spatulatus. Populations in W of range formerly separated as minor, supposedly smaller in size, and those in Arabia once treated as arabicus; only evidence of geographical variation, however, is apparent clinal increase in tail-streamer length from W to E of range#R. Specific name frequently given as feminine, abyssinica, but genus is masculine. Monotypic.
Senegal to Eritrea and E Ethiopia, N to Sahara, and S to edge of rainforest zone in N DRCongo and NW Kenya; occasionally into desert, N to coastal NW Mauritania (Nouadhibou) and NC Sudan (upper R Nile); also SW Arabia (confirmed breeding at least in W Yemen).
